The 9900C combines the performance redefining technologies such as the aluminum Dual Stage rear mounted Heatsink, USA Made Iron Cloth Spider System, 2nd generation V-ROM surround, and more with the immense power of DD’s largest ferrite motor subwoofer series, optimized for a 3200 watt rms and the ability to handle power bursts well over 12,000 watts.
When supercharged, the 9900 motor throws nearly 9000 gauss through a 30mm deep gap, where the 8 layer coil is driven to 40mm of one way travel, with 15mm of coil still driven in the magnet gap resulting in exceptional coil control and excursion driven through the stiffest and lightest moving parts. The Free Flow Cooling System and multi-point heatsinks offer unbeatable heat dissipation to protect the high-temp insulated voice coil. The non-pressed carbon fiber loaded pulp cones are made to be incredibly light and strong, with the audibly distinguishable quality of being handmade in the USA.
The 9921 ups the game further with standard composite cone and 2nd generation EROM high-roll surround. At nearly 30% more cone area than a typical 18 inch sub, the 9921 is the most efficient way to move air with less coil travel, providing the ultimate in sound quality.
